Application filed July 1, 1905. Serial No. 267.876.

'To @ZZ whom it mayvconcrm Be it known that I, CLARENCE W. COLEMAN, a citizen of the United States, and a resident of Westfield, in the county ofUnion and State of New Jersey, have invented certain new and useful Improvements in Signal Apparatus, of

' which the lfollowing is a speciiication.

This invention relates to improvements in signalapparatus especially adapted for use on railways and capable of operation by means e' of an electric motor.

The invention seeks to provide suchan apparatus in which greater simplicity and compactnessof the parts shall be obtained and in r 5.

which there shall be greater reliability and eliiciency and less liability of derangement and improper working of the various parts. lThese objects are secured to a large extent by the particular arrangement of parts whereby the power is applied to the thrust-rod which actuates the signal. f This arrangement makes it possible to dispense with levers, racks, and

chains in moving the signal from one position to another. It makes it possible to applyT the power of the motor directlyto the signal-rod and in the direction of the latters movement,

I energy required to move the signal.

thus effecting a vconsiderable economy in the It also makes it possible to employa magnet or other tlesignal or its thrust-rod'and the motor or device which shall be stationary and have the function of control-ling the connection between motor-driven parts.

' yThis invention also makes it possible to employ a magnet or other device having the lastnamed function and having also the additional functionof controlling the device employed to lock the signal in the position in which it has been moved and having also the function of controlling the supply of energy to the motor.

'Where the invention is applied to operate l ajplurality of signals on. the same post, such as home and distant signals, the advantages above stated are especially marked, one motor serving to operate the signals.

In the accompanying drawings the invention is illustrated in one of its various embodiments and `asapplied to home and distant signals on the same post.

Figure l is aside elevation of the apparatus looking in the direction of the arrow l in Fig.

l 2. Fig. 2 is afront elevation of the apparatus. Fig. 3 is a sidegelevation looking in the direction of the arrow 3 of Fig. 2. Fig. 4 is a sectional plan view taken on the line 4 4 of Fig. 2.. Fig. 5 is a sectional side elevation showing the device for connecting the thrustrod with the motor and for locking the thrustrod in the position to which it has been moved. Fig. 6 is a fragmental side elevation showing the power-wheel of the motor vin the act of lifting the thrust-rod, the view being taken from the side opposite that shown in Fig. 5.

Fig. 7 is a sectional plan view on the line 7 7 of Fig'. Fig. 8 is a sectional plan view on the line 8 8 of Fig. 5. Fig- 9 is a diagram showing the signals and circuits for two blocks of a-railway. A Referring now to the particular embodiment of the invention as shown in the drawings, the frame of the machine consists of the base 1,

back ribs 2 and 3, upper yoke 4, and stirrup 5.

6 is an electric motor which drives gear- Wheel 7 carried on the shaft 8. on which' is mounted pinion 9, meshing with the driv-l ing gear-wheel 10. The shaft 8 is supported by the uprights 1l and l12, bolted to the stirrup 5 at their lower ends and bolted at their upper ends to the yoke 4. These uprights 11 and 12 are provided with bearings for the.

shaft 13, which carries the driving-gear lO.

14 and 15 are the home'and distant signals',

(see Fig. 9,) mountedon the same pst and :operated by the signal-rods or thrust-rods 16 by any suitable means; but as shown in the drawings they are guided by their thrust-rods, which they surround.

22 isa dog pivoted in the piece 2O and yield- IOO ingly pressed toward the 'thrust-rodl by V yspring 23. v

24 is a -U-shaped bracket secured to the side of the thrust rod 16 by screws 25 and 26. Pivoted to the bracket 2 4is a' latch 27, carried on the p in 28and'having'atooth 29 at its upper end andy a roller 30 at its lower end. The

piece 20 engages the thrust-rod 16 to move it upward by the interlocking of dog 22 with tooth 29 of latch 27. The bracket 24 carries also a pivoted dog 31, designed to engage a latchV 32 or other looking' device to lock the thrustrod in its upper position or the position to which it has been moved by the piece 20. The latch 32 is carried on shaft 33, pivoted on the frame and provided with a counterweight 34 and a long lever 35. The lever 35 swings back and forth in the same vertical plane as the roller 30 ot' latch 27.

When the lever 35 is held inward against the roller 30 and the piece 20is moved upward, dog 22 engages latch 27 and moves the thrustrod 16 upward until dog 31 engages latch 32 to hold the thrust-rod in the position to which it has been moved. So long as the lever 35 is held inward against roller 30 latch 32 will maintain the thrust-rod in its upper position. At the same time lever 35 will lock the latch 27 in its engaging position, although the piece 20 may move down from its engagement with the latch 27. It will be seen, therefore, thatl the lever 35 controls the engagement of piece 20 with thrust-rod 16 when the latter is to be moved and also controls the device or means for locking the thrust-rod in the position to which it has been moved.

In the preferred arrangement of the mechanism the piece 2O is operated by a cam and for this purpose has a flange 36, against whose under side the cam moves. 2O constitutes a cam-piece.

37 is the cam, which cooperates with the piece 20. In its best form and as shown in the drawings the cam 37 is in the form of a roller carried on a spoke of the power-wheel 10.

When the rod 16 is in its lower or normal position, piece 20 is resting on the pin 85, between which and the tooth 29 of latch 27 the piece 20 has ordinarily a play of about an eighth of an inch.

38 is a magnetcooperating with an armature on the lower end of lever 35, which nor- Thus the piece mally hangs with its armature against or close to the pole of the magnet.

]n the operation of the parts above described the magnet is energized to hold the lever 35 inward and the motor is started. Lever 35 bears against roller 30, so as to hold the tooth'29 of latch 27 in the path of dog 22 on the piece 20. The latch 32 is also held inward, so as to engage with dog 31. As the power-wheel 10 travels in the direction of the arrow shown in Fig. 6 cam 37 engages with the flange 36 on the piece 2O and carries the piece 2O upward, as shown in Fig. 6. As the piece 20 moves upward its dog 22 engages with the latch 27, and since the latch is locked against movement by the lever 3,5 thrust-rod 16 is carried upward along with the piece 20. During this movement the cam 37 moves from one end of the iiange 36to`the other and back, as shown in Fig. 6, andthe'n out from'under the piece 20, whereupon the motor stops, permitting the piece 20 to drop down upon the stop-pin 85, iixed on rod 16. The spring 39 of the dog 31 permits the dog to snap past locking device 32, so that when the cam passes beyond the piece 20 the thrust-rod is supported on the locking device 32. When lever 35 is released, as by denergizing magnet 38, the weight on the thrust-rod presses latch 32 back out or' the way, so that the thrustrod returns to its lower position. If for any reason the magnet 38 should be deenergized and the motor stopped after the thrust-rod has been more or less elevated and before cam 37 had moved out of engagement -with the piece 20, the thrust-rod would, nevertheless, return to its lower position. In such case if dog 31 has passed latch 32 the latch would be pressed out of the way by the weight ofthe thrust-rod, and the weight ofthe thrustrod bearing on the tooth 29 of latch 27 would cause the lower end of the latch to swing to the left, so as to disengage its Atooth from dog 22. Thus the thrust-rod would be returned to its lower position, although the piee`e2() would be still held in its upper position by the cam 37. It will therefore be seen that the thrust-rod has a movement independent of the piece 20. Thus it will be seen that by this arrangement the signal after having been moved part way or all the way to safety position by the upward movement of the thrust-rod may return to danger at once as soon as magnet 38 is denergized and without regard to the position of the motoror the power-wheel 10 or cam 37 Magnet 38 has an aperture 40, which operates circuit-controllers 41, which control the circuit of the motor, as will hereinafter appear. When the magnet is cnergized,the circuit-controller 41 is closed and when it is deenergized the circuit-controller opens.

42 is a rod pivoted at its upper end to an L-shaped lever 43, which is pivoted at 44 on the yoke 4. The rod 42 is pivotally connected at its lower end with a crank-shaft 45, which operates circuit-breakers 46, 47, and 48.

49 is an arm carrying a roller 50 and secured to the bracket 24` carried on the thrustrod 16.

When the thrust-rod 16 rises and has moved the signal to safety, roller 50 comes against the upper end of lever 43, thereby elevating rod 42 and opening the circuit-breakers 46 and 47 and closing the circuit-breaker 48. When magnet 38 is deuergized to permit the thrust-rod 16 to move downward, roller 50 comes against the depending end of lever 43, turning it back on its pivot to its former position, thereby lowering rod 42 so as to close the circuit-breakers 46 andy 47 and open circuit-breaker 48.

rlhe mechanism for the distant signal 15 operated by thrust-rod 17 is similar to that described with reference to the home signal IOO ISO

. and thrust-.rod 16 lzo described.

one hundred and eighty degrees therefrom.

52 is the latch pivoted on the thrust-rod 17 and corresponding to latch27 of thrust-rod 16. f 53 is the lever corresponding to lever 35 and carrying an armature at its lower end controlled by magnet 54 and controlling-latchf52..l

When this happens, power-- Wheel 10 continues its rotation and cam 51 erigages piecel 21, Which piece connects` with@ ythrust-rod 17 tok put the distant signal to "safety, the distant signal being locked ati safety by the latch 55, as heretofore described. When magnet 38 is denergized,

-thrust-rod 16 is released and the home signal moves to danger by gravity. vVlhen both magnets 38 and'54 are denergized, both signals move to dangen In Fig. 9, v62fand 63 are twoy blocks of a railway provided With signals,- such as here- -ciple. The motor-magnets and other parts 'Y associated .with the lhome and distant signals.

tofore shown and described, the signals being arranged to operate on the normal safety prin- 14 and'15 in Fig. 9 have'thesame referencenumerals as are employed for the corresponding parts in the other figures. 64 is the trackmagnet for block 62. 65 is the track-magnet for block 63. The circuit of the -home-signal I magnet 38 is from battery 66, circuit-controller 67, Wire 68,v Wire69, magnet 38, and'wires 69 and 70 to battery. Since the signals are normally at safety, this circuit, through.

magnet 38z and Which is controlled by trach-` magnet 64, is normally closed. The circuit -of the motor for operating the home signal 14 'is from battery 66, Wire .71circuit-.con-

73, motor 6, and Wire 70 to battery. -The circuit of the motor for thevdistant'signal 15 is `and need `'not be'specilically;

` the motor heretofore traced through circuitvWire L', 'motor 6, 'and Wire`70 to' battery.

' The normally closed circuit of the distant-sig- 51 is the cam-roller cooperating With piece 21 on thrust-rod 17. It is vfixed on the power- `wheel 10 on theopposite side from cam 37 andy breaker 46, wire81, magnet 54, Wires 82,- 69,

70, and 83 back to battery. The operation of the circuits is as follows: When a train enters block 62, it shunts magnet 64 and opens at 67 the circuit of home-'signal magnet 38. 4'When magnet 38 is thus denergized, it unlocks the home and distant signals 14 and 15, *whichhad -been previously locked at safety by their latches 32 land 55, so that the signals rise by gravity to f danger behind the train. As the signals move to danger position circuitbreakers 46 and 47 are opened and circuitbreakers 48 and 60 are closed. When the train passes out of block 62 and into block 63, magnet 6 4 is energized so as to close circuitvcontroller 67. This energizes the circuit of the lhome-signal magnet 38, as heretofore v traced. magnet 38 thereupon closing circuitcontroller 41 and completing the circuit of controller 41 and circuit-breaker 48, this lat'- 'ter circuit-breaker having-*been vpreviously closedwh en'thehome-signal Went to fdanger. The motor' thereupon operates tomove the signalto --saf;ety .and to l'o'ck itthere, asr vheretofore described` When the home signal reaches safety position, circuit-breakers 46 and 47 are restored to` theirw normally closed positions and circuit-breaker 48 isopened,

thereby stopping the motor. ,When the train enters block 63,' it shunts track-magnet 65, which opens circuit-controller 77 and puts the` 4signals for block 63 to v"danger in the same way as described With-reference to signals 14 and 15,.y Circuit-controller 77 is in the circuit of distant-signal magnet 54, and this circuit is againy openedv at circuit-breaker 79 as soon as home Lsignal'84 for block 63 goes to danger. When the train passes out of block 63, circuit-controller 77 closes and home signal 84 is p ut to safety in the same Way as has been describedA Withjreference to home signal 14, thereby closing circuit-breaker 7 9. This completes thefcircuit of distant-signal magnet 54, which then closes circuit-controller 61 and completes the circuit through the motor for the distantfsignah ,This circuit, asv already c traced, extends through.circuit-controllers 41 and 61,;circuit-breaker 60, which Was closed when distant signal went to dangen and throughmotor 6 to battery. Thereupon the motor Voperates to put distant signal 15v to safety and to lock it there, as heretofore described. When the distant signal reaches safety position, the motor-circuit is broken at circuit-breaker 60 and the motor stops.

While this apparatus is herein shownl and describedY in what believed to be its best l form, itwill be understood that the details of the mechanism;M may, ,be v.variously modified IOO tion.
